Chimney Damper Repair Abingdon, MD
A Abingdon chimney sweep can get a stuck damper working again so the fireplace drafts properly and stops leaking heated air. Call (443) 899-3074 to reach a local chimney sweep.
The damper is the movable plate that opens the flue when a fire is burning and closes it when the fireplace is not in use. The most common type is a throat damper, a cast iron or steel plate that sits right above the firebox and opens with a handle or chain. Years of heat and moisture are hard on any damper.
A stuck shut damper means smoke and gases spill into the room instead of rising up the flue. If you light a fire and smoke pours in, open windows, keep people away from the smoke and let the fire burn down, calling 911 if smoke is heavy or anyone feels unwell. A damper should stay open until the ashes are cold.
An open or leaky damper lets heated air escape and cold air come down the chimney. Even when they close, many old throat dampers leave gaps along the edges. A top sealing damper often solves both the seal and the rust problem.
Many chimney damper repair calls in Abingdon also turn up a need for chimney cap installation or fireplace repair.

Call nowThe process
What happens during a damper repair
A damper repair starts with figuring out why it is not working.
Look at the plate
The damper is opened and closed to see where it sticks or fails to seal. Rust and buildup are checked too.
Clean the area
The damper frame and plate are cleaned so they can move freely. Many sticking dampers just need cleaning.
Fix the linkage
The linkage between the handle and plate is fixed so it moves again. A warped plate may not be fixable.
Upgrade the damper
When repair is not practical, a new damper goes in. You will hear which choice makes sense for your fireplace.
Final check
The damper is opened and closed several times to make sure it moves smoothly and seals. You will learn how to operate any new control.
What is included

Cast iron damper repair
Throat dampers that stick or leak are repaired where the plate is still sound.
Handle repair
Broken handles, levers, rotary controls and pins are fixed so you can open the flue easily.
Top mount dampers

Chimney Damper Replacement Abingdon, MD
Some dampers are too far gone to repair, especially when the plate is rusted through or the frame is broken. A new throat damper is possible in some fireplaces, though the opening has to match. For many fireplaces, a top sealing damper is the easier and tighter fit.
Calling (443) 899-3074 from Abingdon with a quick description of the problem helps the sweep plan. If the fireplace has gas logs, say so, since the damper must stay open with vented logs. Ask about the pros and cons of each type.

Top Sealing Damper Abingdon, MD
A top sealing damper mounts at the top of the chimney and closes off the flue with a gasket that seals against the frame. You work it with a handle in the firebox attached to a cable running up the chimney. Some designs combine the damper with a cap and screen.
Sealing the top stops cold air from filling the chimney, which keeps the fireplace area warmer. It helps block rain and animals as well. In very cold weather, the gasket should be checked to make sure it has not frozen to the frame before a fire is lit.

How the weather here affects chimneys around Abingdon
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. The hardest thing on brick here is not the cold itself but the constant swing above and below freezing: water soaks into brick, mortar joints and the crown on a mild day, freezes overnight and expands, and each winter widens the cracks a little more. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. Most homeowners in Abingdon, MD schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Damper Repair FAQ
Can I close the damper when using gas logs?
Vented gas logs need the damper fixed open, usually with a damper clamp, because they produce combustion gases that must escape. Closing the damper with gas logs running can fill the room with carbon monoxide. If you smell gas, leave the house without touching switches and call the gas utility or 911 from outside.
How long should I wait to close the damper after a fire?
The damper should stay open until there are no embers left, often many hours after the fire dies down. Closing it too early can push carbon monoxide into the home. Once the fireplace is cold, closing the damper keeps heated air from escaping.
How does a top sealing damper work?
Top sealing dampers sit on top of the flue and seal it with a rubber or silicone gasket. You open and close it with a handle attached to a cable. It often replaces a failed throat damper.
Is it safe to light a fire with a broken damper?
That comes down to how it is broken: a damper stuck shut makes the fireplace unsafe, while one stuck open mainly wastes heat. One that is stuck open is mostly an energy and comfort problem. Get it repaired before the next fire.
What causes a damper to stick?
Stuck dampers usually come from rust, heavy soot or a warped plate. Problems with the control mechanism are another common cause. The fix depends on what is causing the stick.
